As a key canopy structure parameter, the estimation method of Leaf Area Index (LAI) has always attracted attention. To explore potential to estimate forest LAI from 3D point cloud at low cost, we took photos different angles drone and set five schemes (O (0°), T15 (15°), T30 (30°), OT15 (0° 15°) OT30 30°)), which were used reconstruct based on photogrammetry. Subsequently, values leaf area dist...

Green facades applied on a building’s envelope allow achieving the passive thermal control and energy consumption reduction. These are complex systems many site- plant-specific parameters influence their behavior. The leaf area index (LAI) is relevant plant characteristic to consider. Solar shading latent heat loss of evapotranspiration two main cooling mechanisms. aim this study was assess eff...

The leaf area index (LAI) of three monocultures of Norway spruce (Picea abies (L.) Karst), different in age and structure, was measured by means of two indirect optical techniques of LAI field mapping: 1/ plant canopy analyser LAI-2000, and 2/ digital hemispherical photographs (DHP). The supportive measurements with the TRAC instrument were conducted to produce mainly the element clumping index...
